[S390] cio: fix ineffective verify event



Path verification events occurring for offline devices are currently
ignored. As a result, offline devices are not removed, even though
they might no longer be accessible (for example because the last path
to the device was varied offline). Fix this by scheduling a status
evaluation for the affected subchannel when a path verification event
occurs.
